C'est pour cette raison que j'avais écrit un script de wrapper interactif pour les ordinateurs de bureau Unix. Après un an d'utilisation, je suis ravi de le partager ici!
Fait avec byzanz, gifsicle, xdotoolet le script est écrit dans php.
Exemple de sortie:
[1020px, largeur gif non redimensionnée 1020px, 70 secondes, 50 couleurs, 65Ko ]
Il fournit de bons gifs compressés et constitue une bonne vitrine pour cette question.
Ceci est une base assez simple, prête à être piratée par vous.
Fonctionnalités : Enregistrement GIF aux positions de la souris ou en plein écran, redimensionnement, compression, compression des couleurs, inversion / fusion, téléchargement giphy.com.
Pour commencer un enregistrement gif de 10 secondes: gif 10
Pour enregistrer plusieurs fois avec les mêmes paramètres: gif !
Pour démarrer un enregistrement gif plein écran de 5 secondes: gif 5 --fullscreen
Le script court, s'enregistre agréablement:
[ 45 secondes, largeur 645 pixels, couleurs pleines, 976 Ko ]
Script complet de 5 Ko:
#!/usr/bin/php
<?php
#> php xdotool byzanz gifsicle curl
#@ https://webdev23.github.io/gif/gif

echo "Please move your mouse at the top left corner point\n";
echo "of the wanted gif area. Then press enter.\n";
echo "\n";
